FABBIC-STRIPPTNG MACHINE.

rastreo.

Application filed J 111:9' 1, 1919.

To all whom t may Concern:

lBe it known that I, @Assent lD. Hines, a citizen of the UnitedStates of America, residingat Forth Worth, in the county of Tarrant and State of Texas, 'have invented certain new and useful lmprov'ements in:

Fabric-Stripping Machines, of which the following is aspecilication.

My invention relates to improvements in fabric stripping machines and the object is to provide machines for stripping the fabric from discarded pneumatic tire casings, and t0 provide certain improvements in such machines which will make the main stripping easily and quickly adjustable to different sizes of casings and which will'improve the operation of suoli machines Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out itl the claims.

Reference"is had to the accompanying drawings which form a part of this appli. cation. Figure 1 is a rside elevation of the machine. Fig. '2 is a detail view of the driving elli titl

gear and a counterweight. Fig. 3 is a face view of the adjusting wheel. Fig. il' is a detail view .of "the stripping and adjusting wheels, showing one section of the stripping wheel removed and a section of an adjusting arm. Fig. 5 is a broken sectional view of the same. Fig. 6 is a face view of an adjusting wheel whichdiffers from the wheel shown in the' previous views.

Similar characters or reference are used to indicate the same parts throughout the several views.

This machine is provided with an upright frame 1 and a shaft 2 journaled therein. The stripping wheel comprises a hub 3 having radiating hollow or grooved spokes f1 integral with 4said hub. The rim of the strippingwheel ismade sections 5 and provision is made for moving these sections radially inward and outward so that the wheel may be adjusted for casings of different diameters. The sections 5 have telescoping spoke members 6 which move in the arms or spoke members 4. The members 6 carry stub shafts'or spindles 7. AA disk 8 is .mounted 0n shaft Zand is provided with an irregularly curved groove or curved cam groove -thereinon the side facing the str1pping wheel. Commencmg lat the point 9,

the groove is regularto the pointI 10. The

groove is then diverted inwardly a whole step to the groove 11 which is irregular from the point 10 to the point 13 and regular from the point 13 to the point 12. The groove is then diverted to groove lwhich is irregular from the point 12 tothe point 14, and lthen regular from the point 111 to the end.' -The disk S is loosely mounted on the shaft 2 and mayv be turned by a handle or crank 1b. The spindles or .stulii `shafts `7 project into the irregular groove in' thebdisk 8 and each spindle or stub shaft? is provided with a ball bearing 17 so that the shafts or spindles or eccentric pins 7 will move freely therein without binding or much friction. When the disk Vt3 is turned moved at a time until all are adjusted to the required radius. The stripping wheel can thus be contracted for mounting a tire casing thereon and then expanded for tighteningthe casing thereon., v

The fabric is stripped on a shaft 18. A driving shaft 19 is journaled in the extended frame members 20 and a pulley 21 is made rigid therewith and is driven from the motor 22 by the' belt 23. il. pinion 9.4L is also rigid. with the shaft 19 and this pinion meshes with and drives a ear wheel 25 which is rigid with shaft 18. T eshaft 1S isjournaled in a swinging frame 26 which is pivotally mounted on the axle or shaft 19.

The shaft 18 'can be brought; closer to or moved farther away from the stripping wheel swinging the same on the shaft 19 and held in different positions by 4a rack 27 which may be formed integral with the frame members 20, and by a spring actuated dog 28 which is carried by the lever 29.- The vframe 26 is extended for the purpose of carrying a counterweight 80. A. sheet metal shield or hood 32 for the protecting of the in the groove 33 and move all thesections simultaneously. The groove 33 isi cn- .volute in form so that none of the sections 5. would be of the same distance radially vfrom the center'of the wheel as another section, unless the arms 6 areof gradually in-l creased length.

Inoperation `a portion of; the fabriciis loosened and caught oni'theshaft v18. The machine is then driven to turn the shaft 18 so 'that the fabric will 'be wou-nd Qn the shaft 18,. The sections 5 maybe drawn inwardly riphery, radially movab e A said periphery, -means for moving said arms -for mounting a tire casin and then forced t'ightening the means for driving the same.I

arms carrymg radially consistingl of a disk having an irregular groove in one face and mounted on;

said shaft andlugs'rigid with said arms and projecting in said groove and means for turning said disk, and a stripping shaft and 42. A fabric stripping machine comprising a shaftrl and ya reel thereon, means for expanding the periphery of said reel, a` stripping shaft, a swinging frame for said shaft,

means for driving said shaft, means for positioning said stripping shaft nearer to or farther from said reel, and a counterbalance Weight carried .by said swinging frame for aiding in adgusting said stri-pping shaft. i

In testimony whereof I set my hand, this.
